Persisting Objects containing Objects with PersistenceConstructor causes MappingInstantiationException


    • Type: Bug
    • Status: Closed
    • Priority: Major
    • Resolution: Fixed
    • Affects Version/s: 1.1.1

    • Component/s: Mapping

      Java JDK 1.7u10


      I am able to persist an object and have SringSource re-create the object from the database if all the member variables are primitive types. This holds true if the names of the @PersistenceConstructor arguments don't match exactly the names of the member variables - in this case they an be matched up by using the @Field("foo") and @Value("#root.foo") annotations. However, I get a MappingInstantiationException when I try to persist objects that contain other objects using the @PersistenceConstructor.

      See StackOverflow 13854753 and StackOverflow 13832188 for details.

      According to Oliver Gierke:

      You seem to have found a bug. The value resulting from the first Spel expression evaluation is a DBObject and not actually translated into the parameter type. I've already have some code here locally that fixes that. Would you mind creating a ticket against Spring Data MongoDB to file this as a bug?
